Fifteen patients, whose oesophageal varices had been obliterated by injection sclerotherapy, were examined by double-contrast barium swallow. In nine patients (60%) the oesophagram was abnormal and demonstrated sharp-edged, longitudinal tramline filling defects and an irregular, patchy nodularity with loss of the normal longitudinal folds. These appearances represent redundant epithelial folds, epithelial tags and healed ulcers produced by endoscopic sclerotherapy.
对15例经注射硬化疗法使食管静脉曲张消失的患者进行了双重对比钡餐检查。9例患者（60%）食管造影异常，表现为边缘锐利的纵向条索状充盈缺损以及不规则的斑片状结节，正常纵向皱襞消失。这些表现代表了内镜硬化疗法所产生的多余上皮皱襞、上皮垂片和愈合的溃疡。
